Hi Tony,

I've never found small SAEs to be much interested in BBA, although
they will nibble on the various hair and pelt alga. It also helps
to feed them a moderate amount of fish food. This seems to encourage
them to graze. It's almost as if the young need the nutrition to
steel themselves to confront the less palatable fair. They also
prefer fairly open tanks with little overhead plant cover and a
good current .

Older SAEs will quickly clean up a tank full of BBA. Be patient.
